Linux 3D games run under FreeBSD faster than under Ubuntu

    Comparative performance tests of Ubuntu Linux 11.04 and the "emulator" FreeBSD Linux ABI on PC-BSD 8.2 (this is the version of FreeBSD for desktop computers) showed an amazing result . It turned out that OpenGL games show better performance under FreeBSD than in their native Linux environment. At first glance, this contradicts common sense, because an additional level of abstraction would seem to lower the speed of code execution. But the fact is that FreeBSD Linux ABI is not a virtual machine or an emulator in the traditional sense, but an environment for the native execution of Linux libraries. The tests used systems with an AMD Phenom II X3 710 processor, NVIDIA GeForce graphics cards, see the full configuration



    , performance comparison was carried out using Phoronix Test Suite and OpenGL benchmark Unigine Heaven software for automated performance testing .

    The PC-BSD / FreeBSD system running Linux libraries showed about 8% better performance than Ubuntu Linux 11.04 in tests with a resolution of 1024 x 768, and in tests with a higher resolution, the difference increased to 60%.





    On older benchmarks, PC-BSD / FreeBSD also has an advantage.





    Higher performance FreeBSD has proven itself in real games, especially when activating a higher screen resolution. For example, here are the results with the famous Nexuiz game.
